在长期演进(Long Term Evolution，LTE)和新空口(New Radio，NR)系统中，终端(也即用户，UE)在连接态时需要检测所有时隙中配置的物理下行控制信道(Physical Downlink Control Channel，PDCCH)检测机会(PDCCH monitor occasion)，但是大多数PDCCH检测机会中，基站没有发送PDCCH(数据)，这些PDCCH检测是没有必要的，由于终端进行PDCCH检测需要消耗功率，因此这些PDCCH检测将白白消耗终端能量。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1是本公开实施例可应用的网络结构示意图，如图1所示，包括终端11和网络侧设备12，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定终端的具体类型。网络侧设备12可以是基站，例如：宏站、LTE eNB、5G NR NB等；网络侧设备也可以是小站，如低功率节点(LPN：low power node)、pico、femto等小站，或者网络侧设备可以接入点(AP，access point)；基站也可以是中央单元(CU，central unit)与其管理是和控制的多个传输接收点(TRP，Transmission Reception Point)共同组成的网络节点。需要说明的是，在本公开实施例中并 不限定网络侧设备的具体类型。
为解决基站没有发送PDCCH时终端依然进行PDCCH检测会导致终端功耗浪费的问题，基站可通过节能PDCCH通知UE，在接下来的一段时间是否进行PDCCH检测。例如，基站如果要在接下来的一段时间里发送PDCCH，那么就下发节能PDCCH通知UE在接下来的一段时间里醒来进行PDCCH的检测。
在非连续接收(Discontinuous Reception，DRX)传输中，如果基站为每个DRX周期都配置一个节能PDCCH检测机会，那么会导致时频资源开销的增多和盲检频率的增加。而且，终端需要不停地醒来进行节能PDCCH的检测，不能进入深睡状态。另外，当基站为终端配置了短DRX周期时，终端会根据数据到来情况在长DRX周期和短DRX周期间切换，由于节能PDCCH设置在DRX周期前，长短DRX周期的切换使得节能PDCCH配置(主要是节能PDCCH检测机会配置)变得比较复杂，而且会增加节能PDCCH检测的复杂度。
为解决上述问题，本公开实施例提供了一种节能下行控制信道的传输方案，详见下述。
请参见图2，图2是本公开实施例提供的一种节能下行控制信道的传输方法的流程图，所述方法应用于网络侧设备，包括以下步骤：
201、所述网络侧设备确定第一节能下行控制信道检测机会关联的N个时间段中每一时间段所对应的终端状态，所述终端状态包括醒来状态(也可以称为唤醒状态)和睡眠状态，N为大于1的整数；
也即，本公开实施例中，至少每间隔N个时间段存在一个节能下行控制信道检测机会。
202、所述网络侧设备生成用于指示所述终端状态的节能下行控制信道信息；
203、所述网络侧设备在所述第一节能下行控制信道检测机会下发所述节能下行控制信道信息。
本公开实施例中，所述网络侧设备可以是基站，所述第一节能下行控制信道检测机会可以是即将到来的当前节能下行控制信道检测机会，所述N个 时间段可以是紧随当前节能下行控制信道检测机会的、连续的多个时间段。终端的状态为醒来状态时需要进行PDCCH检测、终端状态为睡眠状态时不需要进行PDCCH检测。节能下行控制信道检测机会，也即PS(Power Saving)PDCCH，或称为唤醒(WUS)PDCCH。
另外，基站在一个节能下行控制信道检测机会可以只下发一个终端的节能下行控制信道信息，也可以下发多个终端的节能下行控制信道信息，也可以说基站在一个节能下行控制信道检测机会下发的节能PDCCH，用于指示一个或多个终端在接下来的一段时间内的状态。针对不同终端，一个节能下行控制信道检测机会关联的时间段数量可以不同，每一时间段的时长、起始时刻和/或终止时刻也可以不同。具体地，基站在一个节能下行控制信道检测机会下发的节能PDCCH包括多个比特，多个终端中的不同终端占用不同的比特。
本公开实施例中，一个节能下行控制信道信息可以指示接下来的多个时间段所对应的终端状态，可以降低终端功耗。另外，与一个节能下行控制信道信息只能指示一个时间段的终端状态方案相比，不仅可以节省时频资源的开销、降低节能PDCCH的盲检频率，从而更加节能，而且终端不需要不停地醒来进行节能PDCCH的检测，便于终端进入深睡状态。并且，与一个节能下行控制信道信息只能指示一个时间段的终端状态方案相比，本申请可以按照较长的时间粒度配置节能PDCCH的检测机会，指示较短时间范围内唤醒和睡眠状态，尤其适用于系统配置了短DRX周期情况，这种情况下，DRX周期会随数据到来情况发生变化，可以按照长DRX周期配置下行控制信道的检测机会，指示到短DRX周期的睡眠和唤醒状态。
需要说明的是，本公开实施例中，下行控制信道可以是物理下行控制信道(Physical Downlink Control Channel，PDCCH)，但对此不作限定，本公开实施例中，下行控制信道可以是指现存的及其将来可能的各种可能定义控制信道，例如：增强物理下行控制信道(Enhanced Physical Downlink Control Channel，ePDCCH)或者机器型通信物理下行控制信道(MTC Physical Downlink Control Channel，MPDCCH)等等。
本公开实施例中，可选地，所述N个时间段的时长之和等于至少一个终 端的长非连续接收周期(也即长DRX周期)，一个所述时间段等于一个终端的短非连续接收周期(也即短DRX周期)。
例如，请参阅图3，针对某一终端，网络侧设备在第一节能下行控制信道检测机会为该终端分配了4个比特来传输节能PDCCH，且该节能PDCCH用于指示四个短DRX周期的终端状态，若该节能PDCCH的4个比特分别为1000，那么其指示终端在该第一节能下行控制信道检测机会之后的4个短DRX周期的终端状态分别为醒来、睡眠、睡眠、睡眠。
在DRX传输中，长DRX周期可以从10ms到10240ms，短DRX周期从2ms到640ms。如果DRX周期配置较小时，网络侧设备可以提前几个DRX周期获知各个DRX周期的终端睡眠和醒来情况，因此可以用一个节能PDCCH指示多个DRX周期的终端睡眠和醒来情况。
本公开实施例中，为简化网络侧设备为终端配置了短DRX周期时节能PDCCH的实现，不区分长DRX周期和短DRX周期，只将一个节能下行控制信道信息与接下来的多个时间段关联。例如，当所述N个时间段的时长之和等于一个长DRX周期时，如果没有配置短DRX周期，那么所述N个时间段对应的终端状态都是睡眠状态或醒来状态，如果配置了短DRX周期，那么所述N个时间段(也即N个短DRX周期)对应的终端状态可以相同也可以不同，具体根据每个短DRX周期内网络侧设备是否发送PDCCH数据来确定。从而，使得存在短DRX周期时的节能PDCCH检测机会配置简单，且能达到节能的粒度为短DRX周期的目的。
另外，本公开实施例中，在进行搜索空间配置时，只需要按照长DRX周期进行搜索空间的配置，可以达到指示短DRX周期的目的，搜索空间配置简单。
下面举例说明上述节能下行控制信道的传输方法。
可选地，所述生成用于指示所述终端状态的节能下行控制信道信息的步骤包括：
若所述N个时间段中至少有一个时间段对应的终端状态为醒来状态，生成用于指示所述终端状态的节能下行控制信道信息。
也即，在本公开实施例中，只有在第一节能下行控制信道检测机会所关 联的N个时间段中需要终端醒来时，才生成并下发节能下行控制信道信息，如果在该N个时间段中都不需要终端醒来，就可以不生成并下发节能下行控制信道信息。对于终端来说，如果没有在第一节能下行控制信道检测机会检测到节能下行控制信道信息，就认为接下来的N个时间段为睡眠状态。
可选地，所述确定第一节能下行控制信道检测机会关联的N个时间段中每一时间段所对应的终端状态的步骤之前，还包括：
所述网络侧设备确定第一信息，所述第一信息包括以下至少之一：
节能下行控制信道检测机会；
所述时间段的数量N；
所述时间段的时间相关信息；
每一终端的节能下行控制信道信息占用的比特数；
每一比特对应的时间段数；
终端的唤醒相关的功能指示信息；
终端的睡眠相关的功能指示信息。
也即，网络侧设备在发送节能PDCCH之前，需要先确定每个终端的节能下行控制信道检测机会，以及每一终端的节能下行控制信道检测机会关联的时间段数量、时间段的时间相关信息(例如时间段的时长、起始时刻、终止时刻、起始时刻偏移和终止时刻偏移值中的至少之一)、节能下行控制信道信息占用的比特数和每一比特对应的时间段数等。另外，网络侧设备还可以预先确定终端的唤醒相关功能和/或睡眠相关的功能。具体地，唤醒相关功能包括但不限于带宽部分(bandwidth Part，BWP)切换、辅小区(Secondary Cell，Scell)的激活、信道状态信息(Channel State Information，CSI)上报触发，多输入多输出(Multiple-Input Multiple-Output，MIMO)天线配置等，信道探测用参考信号(Sounding Reference Signal，SRS)触发、跟踪参考信号(Tracking Reference Signal，TRS)的触发等。
进一步可选地，所述时间段的时间相关信息具体可以是DRX参数，包括长DRX的参数和/或短DRX的参数。
可选地，所述确定第一信息的步骤之后，还包括：
下发所述第一信息。
具体地，网络侧设备可以通过高层信令向终端配置第一信息中所包含的信息。具体地，网络侧设备向终端发送节能下行控制信道检测机会，以使得终端能够在网络侧设备配置的节能下行控制信道检测机会去检测节能PDCCH；网络侧设备通知终端每一节能下行控制信道关联的时间段的数量，从而终端可以根据接收到的节能下行控制信道信息获取接下来的各个时间段的终端状态；网络侧设备通知终端时间段的时间相关信息，从而终端可以对接下来的时间进行分段，并根据节能下行控制信道信息确定各个时间段的终端状态。
可选地，所述节能下行控制信道信息还包括终端的唤醒相关的功能指示信息和/或睡眠相关的功能指示信息。也即，在本公开实施例中，终端的唤醒相关的功能指示信息和/或睡眠相关的功能指示信息可以由节能下行控制信道信息携带。在其他的可选实施例中，终端的唤醒相关的功能指示信息和/或睡眠相关的功能指示信息也可以由网络侧设备预先下发给终端。
可选地，所述节能下行控制信道信息中的每一比特用于指示一个或多个所述时间段对应的终端状态；
本公开实施例中，对于某一终端来说，如果网络侧设备为该终端分配了g个比特来承载该终端的节能下行控制信道信息，且一个节能下行控制信道检测机会对应N个时间段，那么所述终端的节能下行控制信道信息中的每一比特用于指示N/g个时间段。
或者，
所述节能下行控制信道信息中的n个比特用于联合指示k个所述时间段对应的终端状态，n和k为大于1的整数，且n＜k≤N。
本公开实施例中，对于某一终端来说，如果网络侧设备为该终端分配了g个比特来承载该终端的节能下行控制信道信息，且一个节能下行控制信道检测机会对应N个时间段，那么可以使用该g个比特中的n个比特作为组合来指示N个时间段中的k个时间段的终端状态。其中，n可以小于g，相应的k小于N；n可以等于g，相应的k等于N。例如，可以使用2个比特联合指示4个时间段的终端状态，当2比特的取值为00时，指示4个时间段的终端状态为1000(“1”表示醒来、“0”表示睡眠)，当2比特的取值为01时， 指示4个时间段的终端状态为1100，当2比特的取值为10时，指示4个时间段的终端状态为1110，当2比特的取值为11时，指示4个时间段的终端状态为1111。
如果终端没有在第一节能下行控制信道检测机会检测到节能下行控制信道信息，就认为接下来的N个时间段为睡眠状态。那么当一个节能PDCCH丢失时，后续连续N个时间段终端都会进入睡眠状态，不进行PDCCH检测。但是，如果丢失的节能PDCCH指示的是终端醒来进行PDCCH检测，那么就有可能会使得该N个时间段内的PDCCH数据丢失，增加数据时延和时频资源开销。请参阅图4，图4中最上面的图表示终端检测出了节能PDCCH信息，中间的图表示终端漏检了节能PDCCH，最下面的图表示网络侧设备没有发送节能PDCCH，终端没有检测节能PDCCH，PS表示节能PDCCH，GTS表示网络侧设备在节能PDCCH检测机会上没有发送节能PDCCH。
为解决上述问题，本公开实施例中，可选地，所述N个时间段中存在至少一个第二节能下行控制信道检测机会。
也即，网络侧设备除了每间隔N个时间段配置一个节能下行控制信道检测机会外，还在N个时间段中配置节能下行控制信道检测机会，也即第二节能下行控制信道检测机会。网络侧设备可以在第二节能下行控制信道检测机会发送用于指示紧随第二节能下行控制信道检测机会之后的一个或多个时间段的终端状态。从而，即使出现了上述的节能PDCCH丢失情况，也不会导致连续N个时间段内的PDCCH数据丢失的问题，最多只会丢失第一节能下行控制信道检测机会和第二节能下行控制信道检测机会之间的几个时间段内的PDCCH数据。从而，可以提高节能PDCCH的传输可靠性，使得终端可以根据网络侧设备的节能PDCCH信令有效地进行PDCCH数据的检测和接收。另外，还可以降低数据传输时延和重传次数，提高时频资源利用率。
本公开的一些可选实施例中，所述在所述第一节能下行控制信道检测机会下发所述节能下行控制信道信息的步骤之后，还包括：
若在所述第二节能下行控制信道检测机会需要下发节能下行控制信道信息，获取所述第二节能下行控制信道检测机会关联的N个时间段中每一时间段所对应的终端状态；所述第二节能下行控制信道检测机会关联的N个时间 段具体可以是紧随第二节能下行控制信道检测机会之后的N个时间段；
生成并在所述第二节能下行控制信道检测机会下发：用于指示所述第二节能下行控制信道检测机会关联的N个时间段中每一时间段所对应的终端状态的节能下行控制信道信息。
举例来说，请参阅图5，假如一个时间段对应一个DRX周期(可以是短DRX周期，也可以是长DRX周期)，第一节能PDCCH检测机会(图中左起第一个PS和第四个PS)对应接下来的3个DRX周期(从左至右依次为第一DRX周期、第二DRX周期和第三DRX周期)。第二DRX周期和第三DRX周期之前都存在一个第二节能PDCCH检测机会(图中左起第二个PS和第三个PS)。如果网络侧设备确定需要在第二节能PDCCH检测机会下发节能PDCCH时，就获取第二节能下行控制信道检测机会之后的3个DRX周期分别对应的终端状态，然后生成并在第二节能下行控制信道检测机会下发：用于指示所述第二节能下行控制信道检测机会关联的3个时间段中每一时间段所对应的终端状态的节能下行控制信道信息。本示例中，每一DRX周期对应3个节能PDCCH检测机会(一个节能PDCCH检测机会关联N个DRX周期，每一DRX周期就对应N个节能PDCCH检测机会)，也即每一DRX周期的终端状态都可以通过3个节能PDCCH信息来指示。从终端侧来看，终端在每个DRX周期都得醒来接收节能PDCCH，另外，如果上一次接收到的节能PDCCH指示当前DRX周期的终端状态为唤醒，但当前DRX周期前没有检测到节能PDCCH，终端也会执行唤醒操作。
又例如，请参阅图6，假如一个时间段对应一个DRX周期(可以是短DRX周期，也可以是长DRX周期)，第一节能PDCCH检测机会(图中左起第一个PS和第三个PS)对应接下来的3个DRX周期(从左至右依次为第一DRX周期、第二DRX周期和第三DRX周期)。第二DRX周期存在一个第二节能PDCCH检测机会(图中左起第二个PS)，第三DRX周期之前没有第二节能PDCCH检测机会(如果一个节能PDCCH检测机会对应4个或者4个以上的DRX周期，第三DRX周期之前没有第二节能PDCCH检测机会，第三DRX周期以后的DRX周期之前也没有第二节能PDCCH检测机会)。如果网络侧设备确定需要在第二节能PDCCH检测机会下发节能PDCCH时，就获取 第二节能下行控制信道检测机会之后的3个DRX周期分别对应的终端状态，然后生成并在第二节能下行控制信道检测机会下发：用于指示所述第二节能下行控制信道检测机会关联的3个时间段中每一时间段所对应的终端状态的节能下行控制信道信息。本示例中，每一DRX周期对应2个节能PDCCH检测机会，也即每一DRX周期的终端状态都可以通过2个节能PDCCH信息来指示。从终端侧来看，如果上一次接收到的节能PDCCH指示当前DRX周期的终端状态为唤醒，但当前DRX周期前没有检测到节能PDCCH，终端也会执行唤醒操作。
以上举例中，第一节能下行控制信道检测机会和第二节能下行控制信道检测机会的区分只是为了方便说明，两者没有实质上的区别。
本公开的另一些可选实施例中，所述在所述第一节能下行控制信道检测机会下发所述节能下行控制信道信息的步骤之后，还包括：
若在所述第二节能下行控制信道检测机会需要下发节能下行控制信道信息，获取所述N个时间段中在所述第二节能下行控制信道检测机会之后的每一时间段所对应的终端状态；
生成并在所述第二节能下行控制信道检测机会下发：用于指示所述N个时间段中在所述第二节能下行控制信道检测机会之后的每一时间段所对应的终端状态的节能下行控制信道信息。
举例来说，请参阅图7，假如一个时间段对应一个DRX周期(可以是短DRX周期，也可以是长DRX周期)，第一节能PDCCH检测机会(图中左起第一个PS和第三个PS)对应接下来的3个DRX周期(从左至右依次为第一DRX周期、第二DRX周期和第三DRX周期)。第二DRX周期存在一个第二节能PDCCH检测机会(图中左起第二个PS)，第三DRX周期之前没有第二节能PDCCH检测机会(或第三DRX周期之前存在一个第二节能PDCCH检测机会，第二DRX周期之前没有第二节能PDCCH检测机会)。如果网络侧设备确定需要在第二节能PDCCH检测机会下发节能PDCCH时，就获取第一DRX周期、第二DRX周期和第三DRX周期中位于第二节能下行控制信道检测机会之后的2个DRX周期(第二DRX周期和第三DRX周期)分别对应的终端状态，然后生成并在第二节能下行控制信道检测机会下发：用于指示 所述3个时间段中在第二节能下行控制信道检测机会之后的每一时间段所对应的终端状态的节能下行控制信道信息。本示例中，只有部分DRX周期对应2个节能PDCCH检测机会，也即部分DRX周期的终端状态可以通过2个节能PDCCH信息来指示。从终端侧来看，如果上一次接收到的节能PDCCH指示当前DRX周期的终端状态为唤醒，但当前DRX周期前没有检测到节能PDCCH，终端也会执行唤醒操作。
本公开实施例中，一个节能PDCCH检测机会对应N个时间段，相邻的两个或两个以上的节能PDCCH检测机会对应的时间段有重叠，也即一个时间段的终端状态可以通过两个或两个以上的节能PDCCH指示，避免了当一个节能PDCCH丢失时，连续N个时间段终端都错误地进入睡眠状态的情况。
进一步可选地，所述节能下行控制信道的传输方法还包括：
若在上一次发送节能下行控制信道信息之后，未接收到用于指示终端已接收到上一次发送的节能下行控制信道信息的指示信息，则确定需要在所述第二节能下行控制信道检测机会下发节能下行控制信道信息。
也即，在本公开实施例中，虽然网络侧设备为N个时间段配置了两个或者两个以上的节能下行控制信道检测机会(为防止节能PDCCH丢失导致连续N个时间段内的PDCCH数据丢失)，但是并不一定需要在每个节能下行控制信道检测机会上下发节能PDCCH。对于位于N个时间段之间的节能下行控制信道检测机会，只有在判断出终端可能丢失了网络侧设备上一次发送的节能PDCCH时，才需要下发节能PDCCH。例如，可以通过是否接收到用于指示终端已接收到上一次发送的节能下行控制信道信息的指示信息，来判断终端是否接收到上一次发送的节能PDCCH。如果判断终端接收到了上一次发送的节能PDCCH时，就不需要在第二节能下行控制信道检测机会下发节能PDCCH。
本公开实施例中，终端如果没有接收到节能PDCCH，仅仅会在一个时间段或所述N个时间段中的部分时间段内进行睡眠。
具体地，所述用于指示终端已接收到上一次发送的节能下行控制信道信息的指示信息可以为肯定确认(Acknowledgement，ACK)或否定确认(Negative ACKnowledge，NACK)，所述肯定确认或所述否定确认是终端针 对醒来后进行下行控制信道检测的检测结果发送。
本公开实施例中，由于终端如果没有在当前节能下行控制信道检测机会检测到节能下行控制信道信息，就认为接下来的N个时间段为睡眠状态。从而，网络侧设备可以只在需要唤醒终端(也即接下来的N个时间段中至少有一个时间段对应的终端状态为醒着状态)时发送节能PDCCH，终端在根据当前接收到的节能PDCCH醒来进行PDCCH检测时，会针对调度数据(也即PDCCH数据)的检测结果反馈ACK或NACK。因此，如果网络侧设备接收到了ACK或NACK反馈，则说明终端已经醒来进行PDCCH检测(也即终端在DRX活跃期中接收DRX功能定义的下行控制信道)，也即终端接收到了上一次发送的节能PDCCH，即指示ACK/NACK所在DRX周期的节能PDCCH。而如果网络侧设备没有接收到ACK或NACK反馈，则说明终端很有可能没有根据上一次下发的节能PDCCH醒来进行PDCCH检测，也就说明终端很有可能没有接收到网络侧设备上一次下发的节能PDCCH。
可选地，所述获取所述N个时间段中在所述第二节能下行控制信道检测机会之后的每一时间段所对应的终端状态的步骤之前，还包括：
若所述N个时间段中在所述第二节能下行控制信道检测机会之后的时间段，至少有一个时间段对应的终端状态为醒来状态，确定需要在所述第二节能下行控制信道检测机会下发节能下行控制信道信息。
也即，只有在N个时间段中在所述第二节能下行控制信道检测机会之后的时间段需要唤醒终端才下发节能下行控制信道信息，否则可以不下发节能下行控制信道信息，也即如果N个时间段中在所述第二节能下行控制信道检测机会之后的时间段对应的终端状态都是睡眠状态的话，就可以不下发节能下行控制信道信息。针对某一时间段，终端如果没有接收到指示为醒来状态的节能PDCCH，则认为是睡眠状态。由于终端连续两次漏检节能PDCCH的概率极低，因此即使终端漏检了上一次下发的节能PDCCH，这一次节能PDCCH关联的时间段(所述N个时间段中在所述第二节能下行控制信道检测机会之后的时间段)如果对应的终端状态都是睡眠的话也可以不发。
请参见图8，图8是本公开实施例二提供的另一种节能下行控制信道的传输方法的流程图，所述方法应用于终端，包括以下步骤：
801、所述终端在第一节能下行控制信道检测机会接收节能下行控制信道信息；
802、所述终端根据接收到的所述节能下行控制信道信息，确定所述第一节能下行控制信道检测机会关联的N个时间段中每一时间段所对应的终端状态，所述终端状态包括醒来状态和睡眠状态。
本公开实施例中，所述网络侧设备可以是基站，所述第一节能下行控制信道检测机会可以是当前节能下行控制信道检测机会，所述N个时间段可以是紧随当前节能下行控制信道检测机会的、连续的多个时间段。
本公开实施例中，一个节能下行控制信道信息可以指示接下来的多个时间段所对应的终端状态，可以降低终端功耗。另外，与一个节能下行控制信道信息只能指示一个时间段的终端状态方案相比，不仅可以节省时频资源的开销、降低终端进行节能PDCCH盲检的频率，从而更加节能，而且终端不需要不停地醒来进行节能PDCCH的检测，便于终端进入深睡状态。
可选地，所述N个时间段的时长之和等于至少一个终端的长非连续接收周期(也即长DRX周期)，一个所述时间段等于一个终端的短非连续接收周期(也即短DRX周期)。
本公开实施例中，网络侧设备可以按照长DRX周期进行PDCCH搜索空间的配置，能够达到短DRX周期节能的目的。终端进行节能PDCCH检测时，不需要知道DRX周期长短的信息，检测算法简单。另外，从终端侧来看，一个节能PDCCH指示多个DRX周期(可以是长DRX周期，也可以是短DRX)的终端状态，也即终端可以提前多个DRX周期知道睡眠和唤醒状况，从而终端可以跳过多个DRX周期前的节能PDCCH检测，尤其是在节能PDCCH指示为睡眠状态的DRX周期前不执行节能PDCCH检测，进而便于终端进入深睡状态，进一步节约终端能耗。
下面举例说明上述节能下行控制信道的传输方法。
可选地，所述在第一节能下行控制信道检测机会接收节能下行控制信道信息的步骤之前还包括：
接收第一信息，所述第一信息包括以下至少之一：
节能下行控制信道检测机会；
所述时间段的数量N；
所述时间段的时间相关信息；
每一终端的节能下行控制信道信息占用的比特数；
每一比特对应的时间段数；
终端的唤醒相关的功能指示信息；
终端的睡眠相关的功能指示信息。
具体地，网络侧设备可以通过高层信令向终端配置第一信息中所包含的信息。也即，终端可以接收网络侧设备通过高层信令指示的上述信息。
本公开实施例中，如果网络侧设备给某一终端只分配了一个比特来承载该终端的节能下行控制信道信息，那么该节能下行控制信道信息关联的N个时间段内终端一直醒来或一直睡眠。
可选地，所述根据接收到的所述节能下行控制信道信息，确定所述第一节能下行控制信道检测机会关联的N个时间段中每一时间段所对应的终端状态的步骤之前，还包括：
根据相邻两个节能下行控制信道检测机会之间的时间间隔与所述时间段的时长确定所述时间段的数量N；和/或，
根据相邻两个节能下行控制信道检测机会之间的时间间隔、所述时间段的时长和所述终端的节能下行控制信道信息占用的比特数，确定每一比特对应的时间段数。
也即，网络侧设备可以不向终端明确指示所述时间段的数量N(所述第一信息中可以不包括所述时间段的数量N)和/或每一比特对应的时间段的数量，终端在获取相邻两个节能下行控制信道检测机会之间的时间间隔之后，将相邻两个节能下行控制信道检测机会之间的时间间隔除以所述时间段的时长即可得到所述时间段的数量N，将相邻两个节能下行控制信道检测机会之间的时间间隔除以所述时间段的时长再除以所述终端的节能下行控制信道信息占用的比特数即可得到每一比特对应的时间段的数量。另外，如果网络侧设备明确指示了所述时间段的数量N，也可以直接将所述时间段的数量N除以所述终端的节能下行控制信道信息占用的比特数即可得到每一比特对应的时间段的数量。
所述根据接收到的所述节能下行控制信道信息，确定所述第一节能下行控制信道检测机会关联的N个时间段中每一时间段所对应的终端状态的步骤之后，还包括：
在确定为醒来状态的时间段醒来进行下行控制信道检测；
针对检测结果发送肯定确认或否定确认。
另外，可选地，所述N个时间段中至少两个相邻的时间段之间存在第二节能下行控制信道检测机会。
本公开实施例中，终端如果没有接收到节能PDCCH，仅仅会在一个时间段或所述N个时间段中的部分时间段内进行睡眠。例如，如果终端没有在第一节能下行控制信道检测机会接收到节能PDCCH，那么就在第一个第二节能下行控制信道检测机会醒来进行节能PDCCH的检测。在存在两个或两个以上的第二节能下行控制信道检测机会的情况下，如果没有在上一个第二节能下行控制信道检测机会检测到节能PDCCH，那么就会在当前的第二节能下行控制信道检测机会醒来进行节能PDCCH的检测。
可选地，所述根据接收到的所述节能下行控制信道信息，确定所述第一节能下行控制信道检测机会关联的N个时间段中每一时间段所对应的终端状态的步骤之后，还包括：
若所述N个时间段中相邻的第一时间段和第二时间段之间存在第二节能下行控制信道检测机会，且所述第二时间段对应的终端状态为睡眠状态，在所述第二节能下行控制信道检测机会保持或进入睡眠状态。
也即，如果接收到节能PDCCH指示某一时间段对应的终端状态为睡眠状态，那么终端在紧邻该时间段之前的节能下行控制信道检测机会可以不进行节能PDCCH检测。
需要说明的是，本实施例作为与上述实施例一对应的终端侧的实施方式，其具体的实施方式可以参见上述实施例一的相关说明，为了避免重复说明，本实施例不再赘述，且还可以达到相同有益效果。
